Projekat: Interdisciplinarni pristup stvaranju novih sorti soje i unapređenju tehnologije gajenja i dorade semena (MPNTR - 31022)
Sažetak
Novostvorene sorte soje međusobno se razlikuju po morfološkim karakteristikama, zahtevima prema uslovima gajenja i tehnološkom kvalitetu zrna. Navedene razlike utiču na kvalitet semena i njegovu životnu sposobnost. Cilj rada je bio da se utvrdi kvalitet semena novih sorti soje koje se razlikuju u sadržaju proteina i ulja, kao i grupama zrenja. Ispitivanja semenskog kvaliteta izvršeno je na novim sortama soje stvorenim u Institutu za ratarstvo i povrtarstvo, Novi Sad (NS Zenit, NS Virtus, Galina, Valjevka, Diva, NS Maximus, Sava, Balkan, Idila, Rubin, Trijumf i Vojvođanka) u Laboratoriji poljoprivredne stručne službe u Novom Sadu. Od semenskih kvaliteta utvrđen je sadržaj vlage u semenu, nasipna masa i klijavost semena. Sadržaj vlage u semenu, neposredno posle žetve, se kretao od 8,5% do 12,5%, a hektolitarsta masa 65,5 kg/hl do71,3 kg/hl. Između ispitivanih sorata javile su se statistički značajne razlike i statistički najniže vrednosti klijavosti dobijene su kod sorata Sava (78%) i Vojvođanka (79%), a najviše vrednosti kod sorte Rubin (96%), dok je klijavost semena dobijena primenom hladnog testa bila nešto manja.
Abstract
Newly developed soybean varieties differ from each other in morphological characteristics, requirements for growing conditions and technological quality of seed. The mentioned differences affect quality of seed and its viability. The aim of this paper was to determine seed quality of new soybean varieties differing in protein and oil content, and in maturity groups. Testing of seed quality was carried out on new soybean varieties developed in the Institute of field and vegetable crops in Novi Sad (NS Zenit, NS Virtus, Galina, Valjevka, Diva, NS Maximus, Sava, Balkan, Idila, Rubin, Trijumf and Vojvođanka) in the Laboratory of agricultural expert service in Novi Sad. The following seed quality traits were determined: seed moisture content, bulk density and germination of seed. Seed moisture content determined immediately after harvest ranged from 8.5% to 12.5%, and hectoliter weight from 65.5 kg/hl to 71.3 kg/hl. Statistically significant differences were found among studied varieties. The lowest values of germination were obtained in Sava (78%) and Vojvođanka (79%), and the highest in Rubin (96%) variety, while the seed germination determined by applied cold test was slightly lower.
